which of the following best shows how the issue of states rights contributed to the onset of the civil war

Answer 1

One of the most significant ways in which the issue of states' rights contributed to the onset of the Civil War was through the debate over the expansion of slavery into new states and territories. Southern states asserted their right to determine whether or not slavery would be allowed in these areas, leading to conflicts with the federal government and Northern states. This ultimately sparked the secession of Southern states and the formation of the Confederacy, leading to the outbreak of the Civil War.
